- Bump version to 0.2.10 with new sha256
- Use a private OPAMROOT and unset OPAMSWITCH so opam init fetches the real opam repository (the conda-forge opam root only ships an empty repo, which broke 'opam install dune' with 'No package named dune found')
- Build with OCaml 5.5.0 to match the v0.2.10 tag
- Unset LDFLAGS before cmake: native -Wl flags are rejected by wasm-ld

Pull request overview
Updates the xeus-ocaml emscripten-forge recipe to align with upstream v0.2.10 and to make the OCaml/opam bootstrap more reliable during cross-compilation by isolating opam state and adjusting environment flags.
Changes:
- Bumped
xeus-ocamlfrom0.2.8to0.2.10and updated the sourcesha256. - Updated the OCaml build phase to use OCaml
5.5.0and a privateOPAMROOT, while unsettingOPAMSWITCHto ensure opam initializes against the real repository. - Unset
LDFLAGSbefore CMake to avoid passing native-Wl,...flags towasm-ld.
